Inventor
Invention, inventor, etc
They’re subjective terms that mean different thing to different people.
For example, in the world of patents an invention has to be completely novel to the world, and also not obvious to someone practised on the art, which means a problem can’t be solved the way everyone would solve it.
For others, a drone umbrella is an invention. As is a new board game. Or stoned wallabies making crop circles. Or a ute. Mate.
I prefer to reserve the term for breathtaking ideas that have been reduced to practise, and actually work and also have value.
